(BLOOMINGTON) - A Morgan County judge showed no mercy for a man who held a woman hostage with a BB gun.

41-year-old James Robertson will spend the next 30 years in prison.

In January, Robertson walked into an office at a Marsh supermarket - holding a gun and a package believed to be a bomb. He let one female employee go, but held the other hostage. Turns out, the gun he carried was harmless and - so was the package.

Robertson's sentence was handed down after he pleaded guilty to felony kidnapping per plea agreement.
